Japanese Martial Arts at a Glance
Here is how the major arts compare. Each name links to a full guide.
| Art | What it is | Origin | Good to know |
|---|---|---|---|
| Judo | A grappling art built around throws, takedowns, and ground control | Founded in 1882 by Kano Jigoro | A full Olympic sport since the 1964 Tokyo Games |
| Karate | A striking art with punches, kicks, knee and elbow strikes, blocks, and kata (forms) | Developed in the Ryukyu Kingdom (Okinawa); brought to mainland Japan in the early 20th century | Added once to the Olympic program, for the Tokyo 2020 Games, and not retained afterward |
| Aikido | Blending with and redirecting an attacker’s force through flowing joint locks and throws | Developed in the early-to-mid 20th century by Ueshiba Morihei | Generally has no sparring competitions or tournaments |
| Kendo | “The way of the sword,” practiced with bamboo swords | Descended from kenjutsu, the swordsmanship of the samurai | A strike landed in complete silence is not awarded a point |
| Kyudo | “The way of the bow,” Japanese traditional archery | Traditional Japanese archery | Form matters more than hitting the target |
| Sumo | Professional wrestling in which most wrestlers live together in training stables (heya) | Often described as Japan’s national sport | Religious rituals are performed before every bout |
What These Arts Have in Common
Despite their technical differences, the arts share a common structure: ranked belt or grade systems (kyu and dan), formal dojo etiquette including bowing when entering and leaving the training space, and an expectation of gradual, years-long progress under a qualified instructor rather than quick mastery. That shared etiquette is why the arts can look alike to an untrained eye, even though a judo throw, a karate strike, and an aikido wrist lock rest on different foundations. For the values behind them, see how the samurai code still shapes Japanese business culture.
What Connects These Arts
Japanese martial arts are as much about conduct as technique. Bowing at the dojo door, respect for the opponent, and attention to form appear in nearly every guide above, from kendo and kyudo to sumo’s ritual before a bout. That is why many of these arts are described as paths (do) rather than sports, and why they appear in school education and even in discussions of business ethics.
Where to Start
If you are new, read the comparison and the dojo rules first. If you are visiting Japan, sumo’s rituals and stable life help you understand what you are watching.
Frequently Asked Questions
Is karate Japanese?
Karate developed in Okinawa, which was then the Ryukyu Kingdom, before spreading to mainland Japan. See our karate article.
Why do kendo practitioners shout?
In kendo a strike landed in silence will not be awarded a point, so the shout is part of a valid strike. This article explains why.
Does aikido have competitions?
No. Aikido was deliberately designed without competitions or ranked ladders. This guide explains why.
